    "The word reason itself is far from being precise in its meaning. In common and popular discourse it denotes that power by which we distinguish truth from falsehood, and right from wrong, and by which we are enabled to combine means for the attainment of particular ends."

    In Logic, a Proposition is: "A sentence, or part of a sentence, affirming or denying a connection between the terms; limited to express assertions rather than extended to questions and commands." Hyslop defines a Proposition as: "any affirmation or denial of an agreement between two conceptions."

    Hyslop gives the following excellent explanation of the Logical Definition, which as he states is the proper meaning of the term in Logic. He states:

    "The rules which regulate Logical Definition are as follows:

    1. A definition should state the essential attributes of the species defined.

    2. A definition must not contain the name of word defined. Otherwise the definition is called a circulus in definiendo.

    3. The definition must be exactly equivalent to the species defined.

    4. A definition should not be expressed in obscure, figurative, or ambiguous language.

    5. A definition must not be negative when it can be affirmative."
